Exact-match DDR5-6400 ECC RDIMM kit

This 64 GB kit contains two 32 GB DDR5-6400 registered ECC modules built to the precise rank, voltage and timing the GIGABYTE MS04-CE0 motherboard expects. It is intended for administrators upgrading compatible servers that require 288-pin RDIMMs with on-die error correction.

Capacity and headroom

The dual-rank 2Rx8 organisation lets the memory controller address the full 64 GB at the rated 6400 MT/s data rate when populated according to the board's rules. Systems needing more than 64 GB or modules with different ranks, voltages or form factors will not be served by this kit.

Thermals noise and power draw

Operating at 1.10 V without heat spreaders, the modules rely on chassis airflow for cooling in typical server environments. Registered buffering reduces electrical load on the memory controller, contributing to stable operation at the specified CL52 latency under sustained workloads.

Questions about this item

Will this 2Rx8 RDIMM kit run at DDR5 6400 CL52 alongside existing 1Rx8 modules in my GIGABYTE MS04-CE0?

The kit is spec-matched to the GIGABYTE MS04-CE0 at DDR5 6400 CL52 1.1V. Mixing 2Rx8 and 1Rx8 ranks is governed by the board's population rules; consult the motherboard manual for the approved slot order and maximum supported capacity before installing.

How can I confirm the ECC RDIMM kit is operating at its rated 6400 MT/s after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 6400 MT/s (PC5-51200) with CL52 timings and 1.1 V. Registered ECC status should also be reported as active in the firmware or OS memory diagnostics.

Does the 64 GB (2 x 32 GB) package include heat spreaders or any extra cables?

The package contains only the two 288-pin DDR5 RDIMM modules. No heat spreaders, cables, or additional accessories are included.
